Abstract: Method of producing a body (1) for bar feeders, wherein it comprises a first molding step (A) carried out with the aid of a first molding material (M1) in a mold (20) jointly with an overmolding step (B) of a countermold (50), the shape of the mold (20) and/or the shape impressions of the countermold being conceived to achieve in an integral way at least one structural and/or functional element of the said bar feeder.

Abstract: A bar feeding device, for example for a lathe, and a process for using a bar feeding device This bar feeding device comprises: a base extending lengthwise, a channel cover extending lengthwise and rotatably connected to the base, a guiding member comprising a guiding channel extending lengthwise, a pusher flag, a mover, such as an endless chain, fastened to a first end of the pusher flag and able to move the pusher flag lengthwise, a push bar able to move within the guiding channel and fastened to a second end of the pusher flag. The channel cover comprises at least one displaceable member and an displacer for actively displacing the displaceable member relative to the channel cover.

Abstract: The invention relates to a bar feeding device, for example for a lathe. This bar feeding device comprises:—a base (1) extending lengthwise, a channel cover (4) extending lengthwise and rotatably connected to the base (1), a guiding member (7) comprising a guiding channel (8) extending lengthwise, a pusher flag (12), a mover, such as an endless chain (13), fastened to a first end of the pusher flag (12) and able to move the pusher flag (12) lengthwise, a push bar (9) able to move within the guiding channel (8) and fastened to a second end of the pusher flag (12). This bar feeding device is further characterised in that the channel cover (4) comprises at least one displaceable member (14,14a) and an actuator (15) for displacing the displaceable member (14,14a). The invention also pertains to a process for using such a bar feeding device.

Abstract: The device for breaking a glass pane (90) comprises at least one first breaking body (71) that is displaceable along the front side (90a) of the glass pane, at least one second breaking body (72) that is displaceable along the back side (90b) of the glass pane, and a flexible support (49) that serves for supporting the glass pane and that is arranged between the two breaking bodies. According to the method for breaking a glass pane the two breaking bodies are displaced synchronously. The device and the method simplify the production of glass panes of any desired shape, particularly since a template corresponding to the shape is no longer required.
